Masaru Ibuka, the founder of Sony, once said: "Chinese characters are a treasure house of wisdom and imagination." It has been proved that Chinese characters are recognized as the most difficult language to learn in the world, and also the most imaginative and wonderful language. As an international arms raw material giant, Li Guoqin coined the word "tungsten" and made a fortune from it, which is really amazing. Experts believe that this word first appeared in the book Taiping Yu Lan.

Li Guoqin, male, 1887, from Changsha, Hunan. He has been smart and thoughtful since he was a child. 19 1 1 year, when he was studying mining and metallurgy in Changsha Institute of Technology, he happened to have the opportunity to explore tin mines in Wuling Mountain area in southwest China. Li Guoqin was in an inn in a mountain village, but he came across the black stones used on the stove of the shop. These stones were very special in nature. Others are indifferent, but Li Guoqin is serious, so he must ask the shopkeeper to take him to the quarry and see for himself what those black stones are.

In the quarry, he found a rock exposed from the ground. The rocks are black and shiny, and the texture is peculiar, which is the type that Li Guoqin has never seen when he was at school. Therefore, he concluded that there were rich rare metals, but there was no research site and no answer at this time, so Li Guoqin took away a specimen. Li Guoqin then studied at the Royal Institute of Mining in London, England. Under the guidance of trask, the author of British mineral processing textbook, he went to Redras, Cornwall to engage in magnetic separation.

In the studio, he made a new discovery. He got 2-3% ferrotungsten from concentrated tin because of his work task. Of course, at this time, "ferrotungsten" has only one English name, and the Chinese name is not "tungsten". With keen observation, Li Guoqin realized that the composition of "ferrotungsten" was very similar to the specimen he brought to London. After returning to London, he immediately analyzed and tested the ore. The experimental results show that it is indeed a high-quality tungsten-iron specimen with a high content of "tungsten", which surprised Li Guoqin.

Then the war broke out. What is the most lacking in the war? Nature is the raw material of the arms industry-tungsten. Tungsten ore was robbed by belligerents and the price soared. At this time, although China is also rich in tungsten resources, because no one cares, only Li Guoqin understands the wealth contained in it.
